Such an ar- 2.ontsaidmemberflvisa contactportioni t2 with rangement is bulky andinconvenient, and is the which'thejspring'atitslfree'endrhascontactionzocsource of trouble and annoyance each time alamp casion, said portion I 2 being connected intcathm is to bereplaced. Again, the commonly used lamp primary circuit by a wire l3.Again, a wire I4 is connected to and between the receptacle 4 and oneside of the secondary coil, not shown, of the transformer, while a wire15 connects the other side of the latter with the receptacle 4'. Throughthe connections described, or part of them, it is evident, of course,that the primary circuit can be opened or closed by the spring 9.

Attention is now drawn to the fact that, as shown, the receptacles 4, 4due to the coiledwire form thereof are expansible axially by theinsertion of the lamp 5. In Figure 3 it is observed that when not understress the receptacle 4 is a compact cone, the convolutions thereofsubstantially abutting each other, and that the spring 9 of the circuitbreaker is normally distant from the contact portion I2, the primarycircuit, therefore, being open. However, when the lamp 5 is seated insaid receptacles 4, i the coils of both these members are expanded asshown in Figure '7 from the fact that the distance between the apices ofthe cones when the latter are unsprung is less than the length of thesaid lamp. In mounting the lamp one end thereof is first nested in thereceptacle 4', sufficient pressure being exerted to permit the other endto pass to the center of the receptacle 4 and brought into the linetherewith whereupon the receptacle 4' which is under stress will pushthe end at said receptacle 4 of the lamp into that receptacle forseating, and the apex of the cone will be moved toward and against thestrip l0, and by the latter spring 9 is forced into intimate contactwith the conducting portion I2, closing the previously open circuit.

It is to be understood, of course, that the receptacles 4, 4 may beidentical in respect to reaction under stress, and that they are sospaced that the receptacle 4 and the pressure exerted by the receptacle4 will be sufficient to bring about circuit closing.

While the particular structure of the receptacles described answeradmirably the purpose intended it is possible to use some other formyielding like results. Thus it is not the intention to be confinednecessarily to What has'been shown and described in respect thereto. Thesame may be said in respect to other parts herein described.

In placing the circuit breaker 8, 9 in the primary circuit all currentflow through the secondary coil of the transformer, 01- through anyother electric system used, as earlier noted herein, is avoidednaturally, so that no chance harm can be done to the latter by currentflow were the circuit breaker otherwise connected during an intervalwhen the lamp may not be in place.

I'claim:

Means for mounting a lamp and for closing a circuit therethrough,including in its construction, and in combination with the primary andsecondary coils of a transformer, a normally open circuit breakerconnected in circuit with the primary coil, a receptacle erectedadjacent the circuitbreaker normally free thereof, part of saidreceptacle being yieldably extensible toward said circuit breakeradapted to abut upon the same to close the primary circuit therethroughby a lamp inserted at one end into said receptacle, and means tomaintain elastic pressure endwise uponthe lamp in the direction of saidcircuit breaker to maintain closed relation thereof, said receptacle andsaid means being connected with the secondary coil, closing the circuitthrough said lamp.

2. Means for mounting a lamp and for closing a circuit therethrough,including in its construction, and in combination with the primary andsecondary coils of a transformer, a normally open circuit breakerconnected in circuit with the said primary coil, a receptacle erectedadjacent the circuit breaker normally free of the same, part of saidreceptacle being yieldingly extensible toward said circuit breaker andto abut upon the same to close the circuit therethrough by introductionof one end of a lamp into said receptacle, and a second receptacle atthe other end of the lamp, the same adapted to exert a yielding pressureon said lamp in the direction of said circuit breaker to maintain aclosed primary circuit, both receptacles being in circuit with saidsecondary coil'through said lamp.

3. Means for mounting a lamp and for closing a circuit there-through,including in its construction, and in combination with the primary andsecondary coils of a transformer, a normally open circuit breakerconnected in circuit with the P mary coil, a receptacle erected adjacentthe circuit breaker normally free thereof, said receptaole consisting ofa helix of spring wire, part of said receptacle being yieldablyextensible toward said circuit breaker adapted to abut upon the same toclose the primary circuit therethrough by a lamp inserted at one endinto said receptacle, and means to maintain elastic pressure endwiseupon the lamp in the direction of said circuit breaker to maintainclosed relation thereof, said receptacle and said means being connectedwith the secondary coil, closing the circuit through said lamp.
